Given a string s with all lower case characters, find the length of the longest palindromic subsequence in s.

Given lowercase alphabet strings a, b, and c, return the length of their longest common subsequence.

Given lowercase alphabet strings s and t of the same length, return whether there’s some anagram of s, say a, and some anagram of t, say b, such that:

You are given a list of unique integers nums that is sorted in ascending order and is rotated at some pivot point. Find the maximum number in the rotated list.

Given a binary search tree root, replace every node’s value v by its value plus the sum of all other values in the tree that are greater than v.

You are given a two-dimensional list of integers rooms. Each index i in rooms represents a room and rooms[i] represents different keys to unlock other rooms.

Spreadsheets often use this alphabetical encoding for its columns: "A", "B", "C", …, "AA", "AB", "AC", …, "ZZ", "AAA", "AAB", "AAC", ….

Given a binary tree root, consider deleting an edge in the tree so that the tree becomes disjoint with two trees. Then, take the sum of each subtree and mult...

You are given a list of integers prices where prices[i] represents the price to sell a rod of size i + 1, and an integer n which represents the current size ...

Given a list of integers nums sorted in ascending order, remove in-place duplicates that appear more than twice.

Given a binary tree root, find the most frequent subtree sum. The subtree sum of a node is the sum of all values under a node, including the node itself. You...
